The diff-pair placer creates DIFF_PAIRs on the stack, which have
VIAs in them, which have HOLEs in them. The HOLEs get put in the
NODE's index, and we then crash later when doing a collision after
the stack variable has gone out of scope.
The stack variable is also copied while doing a search for "best",
and without the operator= definitions the "best" and the "original"
both think they own the HOLE.

(They were only getting drawn on top of the selection shadow when
drawn by their parent symbol because LIB_FIELD was correctly
setting the view layers but SCH_FIELD was not.)
We need to check if a lockfile is valid to determine if we should
override the lock. Valid() is true if the lockfile couldn't be created
b/c of permissions or if the lockfile could be created and acquired.
This was causing intermittent shove hiccups/freezes as RULE_RESOLVER::GetClearance() could return a bogus clearance value, taking
a cached value for an item that does not exist anymore. If the allocator/stack accidentally reclaimed such item's address - we were getting
very nasty and difficult to reproduce misbehaviours of the shove algorithm. Hopefully this patch fixes this. More info in the comments.
Note to self - I'm still not fully convinced I want PNS::ITEM pointers as the cache key, probably a unique counter would be better here.
When editing or viewing library symbols, the files are watched for
underlying changes. If any occur, the user is either prompted to reload
(if reloading would overwrite their current edits) or the file is
silently updated to the current version on disk.
This also sets a custom assertion handler to avoid unneeded crashes when
recieving invalid SAMBA packets and turns off assertions entirely when
running in release (non-debug) mode
We don't need to lock in import because we are creating a new file. We
should, however, show the locking user/machine when opening in schematic
editor and take over the lock if they want to proceed.

The root cause was not removing the original (pre-dragging) via from the world, comparing the ITEM::Parent() pointers of the items was only hiding the main issue.
This also fixes the PNSViaCollisions test in the qa/ suite.
1) Also reorders parameters to make sure the compiler helps out.
2) This also makes it harder to mess up the discrepency between
BOX2I/wxRECT/etc::Inflate() and SHAPE_POLY_SET::Inflate.
3) Also fixes a couple of bugs where the corner strategy was passed
in as a segCount.
4) Also fixes a couple of bugs where the error wasn't forced to the
outside to match the ERROR_LOCATION.
5) Also fixes a couple of bugs where the seg count was specified
without regard to an already passed-in max deviation
